Since intermolecular forces is stronger in a solid than a liquid, then NaCl has stronger intermolecular forces than H2O.
Intermolecular forces exists between molecules of the same or different kinds. Water has a dipole moment hence it can interact effectively with the ions in NaCl. This leads to an ion dipole interaction that results in the dissolution of NaCl in H2O.
NaCl is a solid and water is a liquid. Since intermolecular forces is stronger in a solid than a liquid, then NaCl has stronger intermolecular forces than H2O.
Hence, the best argument that compares the intermolecular interactions in water and NaCl is; salt is a solid and water is a liquid, so water has stronger intramolecular forces.

The density of gold is 19. 3 g/cm3. What is the volume of a 13 g gold nugget? (Density: D = ). 25 cm3. 67 cm3 1. 48 cm3 2. 50 cm3.
Answer:
0.67 cm³Explanation:
The volume of a substance when given the density and mass can be found by using the formula
[tex]volume = \frac{mass}{density} \\[/tex]
From the question
mass = 13 g
density = 19.3 g/cm³
We have
[tex]volume = \frac{13}{19.3} \\ = 0.673575...[/tex]
We have the final answer as

Explanation:
NaC2H3O2 HOH --> HC2H3O2 NaOH Since the two products are a weak acid and a strong base, we expect this mixture to be basic. When NaF reacts with water in the same manner, the products would be NaOH and _______.
The products of the reaction would be NaOH and HF
From the question,
We are to determine the products of the reaction between NaF and water in the same manner as the given reaction.
To determine the other product, we will write the equation for the reaction
The equation for the reaction is
NaF + H₂O → NaOH + HF
Hence, the products of the reaction would be NaOH and HF.

Based on the law of conservation of mass, which of the following statements is correct? (5 points)
a
Matter is neither created nor destroyed.
b
Matter can be created but it cannot be destroyed.
The total mass of substances before a reaction is less than the total mass after a reaction.
The total mass of substances before a reaction is greater than the total mass after a reaction.
Matter is neither created nor destroyed. Therefor, option (A) is correct.
What is The Law of Conservation of Mass?The Law of Conservation of Mass is a fundamental principle in science that states that matter cannot be created or destroyed in a chemical reaction, only transformed from one form to another. This means that the total mass of the reactants in a chemical reaction must be equal to the total mass of the products.
The Law of Conservation of Mass was first introduced by Antoine Lavoisier, a French chemist, in the 18th century. The law has been extensively tested and verified through numerous experiments in the field of chemistry. It is an essential concept for understanding the behavior of matter in chemical reactions and for the development of technologies that depend on chemical reactions, such as energy production, medicine, and materials science.

Out of the choices listed, oxygen is the only element. The other choices are incorrect because air is a mixture of nitrogen, oxygen, carbon dioxide, water vapors, and some other gases; water is a compound of hydrogen and oxygen; and sodium chloride is a compound of sodium and chloride ions; meanwhile, oxygen is a pure element.
why are metals generally good conductors of electric current?
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
Because the atoms in metals form a matrix through which outside electrons may easily travel, metals are good conductors of electricity and heat. They generate a sea of electrons around the positive nuclei of the interacting metal ions, rather than circling their particular atoms.
The free flow of shared electrons can carry an electric current through a metal. Carbon atoms join with iron atoms to create bonds.
as liquid or gases heat up, they ___________. Then as they___________ they fall, thus As liquid or gases heat up, they driving the motion the of convection.
A: Fall, Heat

Why is it important that you not breathe on the baking soda test?
Baking soda is a salt of sodium and bicarbonate ions. In a soda test, the breath will raise the temperature as it contains water vapor and decomposes the soda.
What is the baking soda test?The baking soda is also called sodium bicarbonate, and the test uses sodium bicarbonate as a reactant. It is also a leavening agent that is used in the preparation of food.
Breath contains some amount of water vapor that alters the test by diluting it and resulting in the clouding of the test. The water vapor decomposes the baking soda and alters the test results.
Therefore, breath contains water vapor.

How does calculating the kinetic energy of an object at different velocities help understand the relationship between kinetic energy and velocity?
Answer:
Kinetic energy depends on the velocity of the object squared
Explanation:
Kinetic energy depends on the velocity of the object squared. This means that when the velocity of an object doubles, its kinetic energy quadruples. ... Kinetic energy must always be either zero or a positive value. While velocity can have a positive or negative value, velocity squared is always positive.

What is the molarity of a NaOH solution if 48.0 mL of a 0.220 M H2SO4 solution is required to neutralize a 25.0-mL sample of the NaOH solution?
Answer:
Molarity NaOH = 0.85M (2 sig figs)
Explanation:
48.0ml(0.220M H₂SO₄) + 25ml(Xmolar NaOH)H₂SO₄ + 2NaOH => Na₂SO₄ + 2H₂O
2(molarity x volume) H₂SO₄ = (molarity x volume) NaOH
2(0.220M x 48.0ml) = 25.0ml x Molarity NaOH
Molarity NaOH = 2(0.220M x 48.0ml)/25.0ml = 0.8448M ≅ 0.85M (2 sig figs)
